The description will rely on two figures:
• Figure X.4.2.1-1 represents the evolution of the Workflow Document during this Referral
workflow. Each one of the three steps A, B, C is depicted in a column.
• Figure X.4.2.1-2 is a sequence diagram of the transactions between “system actors” in the
sharing of the Workflow Document as it is updated, using an infrastructure based on the
XDS profile (although not shown here, this use case could be transposed on the XDR or
XDM profiles).
X.4.2.1.1 Referral Workflow Use Case - Step by Step
We present below the detailed chronological sequence of steps:
A. A physician refers a patient to another healthcare provider for a specialist’s
consultation
In this task, the GP examines the patient and reviews the patient’s most recent laboratory report.
The GP refers the patient to a specialist, creating an eReferral document and referencing the
laboratory report.
The GP’s software, as Content Creator, produces the e-Referral Document and one Workflow
Document to track the clinical workflow of the eReferral. As shown in column A of Figure
X.4.2.1-1, at this moment the Workflow Document created has only one task (“requested”)
characterized by:
• a status “completed”
• as inputs of the task the references to the laboratory report analyzed by the GP
• as outputs of the task the reference to the eReferral document produced.
In order to share the documents produced during the task, the GP’s Software (as a grouped
Content Creator and XDS Document Source) submits the eReferral Document and the Workflow
Document to the XDS Document Repository as shown in box A of Figure X.4.2.1-2.
